Claims.

The invention relates to .transparent display and filing devices forphotographs, cards, samples, stamps and the like.

In my priorpatents various devices for mountingand filing slips,.papers,cards, samples, photo .graphs, etc. in overlapping order have beendisclosed, whichhave generally included a backing of comparatively stifimaterial such as album leaves or covers and one ormore strips of tough,flexible material gummed thereon, which strips include tongues or tabsto which the cards or .otherarticles are to be adhesively secured. Sucharrangement is shown for example in my Patents Nos. 1,862,450 dated June7, 1932; 2,142,261dated January 3, 1939; and 2,204,098 dated June 11,.1940.

It .is frequently desirable to place the articles to .be filed inenvelopes from which they may be removed if desired and to secure theenvelopes to the tongues or tabs in overlapped order. Several suchsystems are disclosed in my prior patents, see for example Patent No.2,149,488 dated March 7, .1939. This is a comparatively simple matterwhere ordinary paper envelopes are employed. However, it is desired insome cases to employ envelopes composedof transparent materialpreferably a cellulose ester suchas cellulose acetate, nitro-celluloseand the like so that the contents of the envelope may be displayed. Ithas been found that envelopes composed of such material will not adhereto tongues or tabs gummed with the ordinary adhesive such as that withwhich the rear surfaces of the flexible mounting strips of my priorpatents are generally coated. Theso-called dry sealing adhesives,generally having a dispersed rubber or latex base will cause adhesion ofsuch transparent materials, but it would be undesirable to provide thetongues of the filing device shownin my prior patents with such adhesiveas the tongues would then adhere to the still backing and would not beaccessible for filing purposes.

The :object of the present invention is accordingly-to provide a simpleand effective means for mounting'transparent envelopes which would notadhere to the ordinary adhesive, upon mounting tongues '01 tabs such asthose shown in my prior patents. This .I accomplish according to thepresent invention by the use of a strip of adhesive tape of the drysealing type, generally referred to as Scotch tape, gummed on both sidesand employed for the dual purpose of securing together the edges oftwo'sides of a transparent sheet to form the envelopes, and .forsecuring the envelopes to the tongue or tongues'of the mount- .mountingor filing strip ll flexible material such as cloth, paper or the likeany of the forms disclosed .member l0 and is provided envelopes so thatno portion of the adhesive is exposed.

The invention will be more readily understood by reference to theaccompanying drawing and the following detailed description which areintended as illustrative of the inventive thought involved rather thanas limiting the invention to the particular details'set forth.

In the drawing:

Fig.1 shows an open album or other book havingtransparent envelopesassembled in overlapping order in accordance with the present invention.

Fig. 2 is an end view showing the manner in which the edges of theenvelopes grip the tongues of the mounting strip between them.

Fig. 3 is a detail view on an enlarged scale showing an envelope .in theprocess of being mounted.

Fig. 4 is a viewshowing a transparent sheet from which anenvelope is tobe formed having a gummed strip applied to one edge thereof.

Fig. 5 is a detail view showing the gummed .strip.

Fig. 6 .is a detail showing the modification wherein a clip is employedto hold the edges of the, envelopes together.

Fig. .isa detail view showing the mounting of an envelope upon adifferent form of tongue or tab.

Fig. .8.is a view illustrating .a plurality of envelopes secured tomounting strips of the type shown in Fig. 7.

Fig. 9 is a view showing .a modification in which one end ofotheenvelope is closed and the other open.

Fig. 10 isa view similar to Fig. 6, in which the corners of the tapededge are permanently secured.

Referring to the drawing, the reference numeral l0 denotesa suitablestifi" backing such as one of the :covers or .a leaf of a photograph orstamp album .or the like,.such as is shown in my prior Patent No.2,204,098. .To this backing a of relatively tough is adapted to beapplied which strip may be of in my prior patents. This strip isadhesively secured to the backing with tabs [2 integral with the strip.These tabs are adapted to be bent outwardly from :the .backrfor thepurpose of mounting cards, photographs, envelopes or the .Fig. 5.

like and to facilitate such bending operation transverse score lines maybe employed if desired. These tongues have been previously employed formounting cards, photographs, slips, paper envelopes and the like butaccording to the present invention a transparent envelope A composed ofmaterial which would not ordinarily adhere to the adhesive on the backof the tongues I2 is adapted to be secured to these tongues or tabs, theenvelopes being preferably open at opposite ends I3 so as to permitinsertion of photographs, pictures, samples, stamps or the like B whichare readily accessible and both sides of which are visible through thetransparent envelopes.

The envelope is preferably made from a sheet I4 (Fig. 4) of transparentmaterial such as cellulose acetate, Celluloid or the like, and isadapted to be formed into an envelope by folding about a center line I5bringing together the two opposite edges IB and IT. This foldingoperation is generally not performed until the envelope is about to beapplied to the tongues although if desired the blank may be initiallyfolded about the center line and furnished in this form to the user.

In order to secure proper adhesion between the edges I6 and I1 and atthe same time secure the envelopes to the tongues I2 of the mountingstrip II, an adhesive strip I8 of Scotch tape or the like, gummed onboth sides with a dry adhesive, is provided, such strip being shown inThe gummed strip i preferably first applied to one edge ll of the sheetI5 either prior or subsequent to folding about the center line, andafter the strip had been applied the edges of the transparent sheet arebrought together as best illustrated in Figs. 2 and 3 so as to embracethe adhesive strip I8 and the tongues I2 between them. In this mannerthe tongues are adhesive- 1y secured to the strip I8 and at the sametime the two edges of the sheet are held together by the adhesive stripat the portions I9 between the tongues and at those portions 20extending beyond the tongues.

Any suitable form of tongues may be employed such as are shown in myPatents Nos. 1,862,450, 2,142,261 and 2,204,098. In Figs. 7 and 8 theenvelopes are shown applied to mounting strips similar to those shown inFig. 10 of my Patent No. 2,204,098, the tongues I2a being partiallyseparated from the body of the strip IIal by slits 30. The strips Ilaare adapted to be mounted one below the other as illustrated in Fig. '7of my aforesaid patent and in Fig. 8 of the present drawing.

When the envelope A has been secured in place, photographs, stamps orthe like B may be inserted through the open ends of the envelope. Eachenvelope and its contents may be turned about the tongues or tabs 52 orI2a as described in my prior patents, thus rendering either sidevisible. It will be obvious that two photographs or the like may besecured in an envelope back to back or memoranda may be placed on thebacks of the photographs or the like and either side may be viewed asdesired.

While the adhesive strip I8 is in general sufficient to hold the edgesI6 and i1 together, an additional fastening means such as a paper clipor the like 25 may be employed at each end, particularly where theadhesive strip and envelope do not extend far beyond the tongues I2 orIZa. In this way any possibility of separation at the end of the stripis avoided.

By the use of non-drying adhesive upon the strip I8 the envelope may besecurely retained in the album as long as desired but if for any reasonit should be necessary to remove the envelope this can be accomplishedwithout mutilating the tongues I2.

The invention has been described in detail for the purpose ofillustration but it will be obvious that various modifications andvariations may be resorted to without departing from the spirit of theinvention.

For instance, it may be desirable in certain cases to close one end 26of the envelope as indicated in Fig. 9. The closure may be accomplishedby means of stitching, by securing the edges with tape or the like, bythe use of replaceable clips or other suitable means may be employed.

Also instead of the removable clip 25 at each corner of the tape asindicated in Fig. 6, a relatively permanent fastening means may beemployed as for example a row of stitching 25a as indicated in Fig. 10.
